Method Description
distance ( float aX, float aY, float bX, float bY ) : float

distance ( int aX, int aY, int bX, int bY ) : float

round ( float d ) : int

Ends up being a bit faster than {@link Math#round(float)}. This merely rounds its argument to the nearest int, where x.5 rounds up to x+1. Semantics of this shortcut differ slightly from {@link Math#round(float)} in that half rounds down for negative values. -2.5 rounds to -3, not -2. For purposes here it makes no difference.

sum ( int array ) : int
